William C. Mitchell was born in Connecticut, on December 28, 1925, attended elementary and high schools also in that state. As a teenager, he spent over 3 years In U. S. Navy as a radar technician. After receiving additional instruction at the Naval Research Labs on top secret radar countermeasures equipment (the birth of what is now called electronic warfare) and taught that subject a for year at the Pacific Fleet Schools in Hawaii.

He graduated from the University of Connecticut, with a B. S. in Engineering in 1950, elected to honorary engineering societies Eta Kappa Nu and Tau Beta Pi. (By age 24 he had graduated from high school, spent over 3 years in the Navy, graduated from college, was married, had an engineering position, and a son.)

He worked as a radar design engineer at Bendix Radio Corporation in Towson, Maryland and at Gilfillan Brothers and Litton Industries in the Los Angeles area for about 10 years. Later was Chief Engineer of a small company specializing in digitally controlled industrial processing, that is, computerization of processes such as automatic gasoline blending at refineries as early as 1960.

The last 19 years of his full-time employment as Sub-Project Engineer, and later as Project Engineer at TRW Systems in Redondo Beach, California was primarily on NASA scientific spacecraft programs. But he also worked (in 1975) on such projects as the establishment of technical requirements for a new Pacific Fleet Commander In Chief headquarters (CINCPAC) in Hawaii, and (in 1979 to 1981) on the installation of the NASA Data Tracking and Relay Satellite System (TDRSS) ground station at White Sands, New Mexico.

Following retirement from TRW (in 1981), he worked as a consultant engineer on several spacecraft programs, but also on such projects as the computerization of FBI Identification Division data information storage and retrieval in Washington, DC.

Although never fulfilling requirements for an advanced degree, Mitchell completed a number of graduate courses in mathematics, science and engineering during his years of employment. He has in the past been an airplane pilot, with commercial license, instrument rating, and aerobatics training; and a Cessna aircraft owner. Other interests have included, music, swimming, boating, fishing and skiing. Of special interest has been family; including Holly, his wife of 53 years, son, daughter, and grandchildren.

He became heavily involved in cosmology in the mid-1980s and, after considerable study, became disenchanted with Big Bang Theory. Since then he has worked full-time on cosmology, and wrote a number of papers on that topic. In the mid-1990s, he wrote The Cult of the Big Bang, and, for the past 3 years, has devoted his efforts to the preparation of this book, Bye Bye Big Bang - Hello Reality.
